Question
Chapter 11, Problem 22P
Interpretation Introduction
Interpretation:
The difference in the structures of glycogen and cellulose needs to be explained.
Concept introduction:
Carbohydrates are available in various forms like starch, cellulose, glycogen etc. They all are polysaccharides which contribute as an energy source in plants and animals. The human body needs sufficient intake of sugar or glucose which is an energy source of human cells. Glycogen and cellulose are the polysacchrides formed by sugar molecules called glucose. They are a good source of energy.

. Provide an explanation for the fact that a-D-mannose is more stable
than B-D-mannose, whereas the opposite is true for glucose.
A picture of the two disaccharide repeats of hyaluronic acid are shown below.
Name the two different glycosidic linkages. Are these the same linkages as those found in glycogen?
This is DNA. Locate the nitrogen bases (nitrogens are blue). Where are they located in the molecule?Locate the sugars and phosphates, and describe their location. Adjacent nucleotides are linked by covalent phosphodiester bonds (-O-P-O-) produced by a condensation reaction. What parts of the adjacent nucleotides are linked by phosphodiester bonds?Two nitrogenous bases extending towards the middle of the double helix. Are there any covalent bonds between these bases?If there are no covalent bonds between these bases, what other kinds of bonds might hold the two strands of the double helix together?
